Suppression management is an important task whenever you are targeting a set of audience to receive your emails or sms or push notifications through any channel or any tool. With the latest laws like CAN-SPAM and the fines associated with it it’s of more significance for people who are not meant to to not receive emails than people actually receiving it as the fine associated with former is much more than the revenue generated by the latter. Auto-Suppression is a functionality provided by Salesforce Marketing Cloud where you can prohibit people from receiving emails via automation. Just prepare a list, feed into the system and they would be left out from every email going out of your software.

Some pointers-

Use an auto-suppression list when you want to assign a suppression list to be used across the entire enterprise or for specific business units for specific send classifications.

You can assign auto-suppression lists at different levels of your account.

select the CAN-SPAM classification type- Commercial, transactional or to both

select the business units you want the suppression to happen

click on Save

Adding members to list- We cannot import via manual transfer in the auto-suppression list like we do in a data extension. Import can be done only through a import job which will directly insert the records into the list.

Create a .csv file with 2 colums – ‘Email Address’ and ‘Event Date’. 1st columns is a required field while 2nd is just for record purpose. Put the file on your FTP location

go to email tab in marketing cloud

click on Interactions>Import

Fill in the details

select the FTP location defined for this file

select the file-type and provide a filename which matches to the filename on your FTP location

select Data Extension radio button

select the auto-suppression configuration option

select your list you just created

select the import type as add and update or overwrite as per business requirement
